A PDA-style mini pocket pc
July thirteenth, 2022—
For a time within the late Nineteen Nineties and early 2000s, PDAs (private digital assistants) had been fairly common. However smartphones made PDAs out of date, as even early fashions had much more performance. Lots of as we speak’s microcontrollers have efficiency just like early PDAs and Volos took benefit of that to construct an Arduino Nano-based mini pocket pc harking back to a basic PDA.
PDAs — particularly early fashions — had been way more restricted than smartphones. Their options had been extra akin to what we name “dumbphones” as we speak, besides with none form of WiFi or mobile connectivity. They normally solely had a handful of “apps,” comparable to a calendar, watch/timer, calculator, and notes. Later PDAs would come with some connectivity choices and the power to ship emails, however this mini PC is extra like the primary technology of PDAs just like the Psion Organizer from the ’80s.
An Arduino Nano board controls all of this gadget’s features. It attaches to a customized PCB that doubles because the physique of the gadget. The PCB additionally incorporates a small OLED display in portrait orientation, three buttons, a potentiometer, an LED, and piezo buzzer. Volos designed the PCB in order that two boards can stack, separated by stand-offs, with the LiPo battery sandwiched in between. Volos programmed some fundamental PDA apps that make the most of customized libraries which maintain reminiscence utilization down.
In the event you’re inquisitive about constructing your individual Arduino Nano mini PC, Volos revealed the entire recordsdata you want on his GitHub web page.
